The rain fell softly tonight. A shadow slipped through darkness. The old house creaked loudly. A chilling draft swept past. Footsteps echoed on hardwood floors. A single candle flickered weakly. Shadows danced on cracked walls. A clock ticked, slow, menacing. A door opened with hesitation. Cold air rushed inside swiftly. A figure stood cloaked, silent. Blood pooled on the carpet. A scream pierced the stillness. The killer vanished without trace. Investigation loomed over the mansion. Secrets whispered through the halls.
